Control of a dual-layer loudspeaker array for the generation of private sound
Control of a dual-layer loudspeaker array for the generation of private sound
A dual-layer loudspeaker array has been constructed and controlled in order to ensure directional radiation over only one hemisphere of the region surrounding the array. This enables the generation of a “private sound field” for one or a few persons situated in a certain spatial region relative to the array. The paper compares the performance of two conceptually different types of algorithm. The performance of the control algorithms have been compared theoretically and investigated by using computer simulations. The same control algorithms and the simulations have been experimentally verified with the prototype dual-layer array composed of 16 loudspeakers. Excellent agreement between experiment and theory is achieved.

Abstract
A dual-layer loudspeaker array has been constructed and controlled in order to ensure directional radiation over only one hemisphere of the region surrounding the array. This enables the generation of a “private sound field” for one or a few persons situated in a certain spatial region relative to the array. The paper compares the performance of two conceptually different types of algorithm. The performance of the control algorithms have been compared theoretically and investigated by using computer simulations. The same control algorithms and the simulations have been experimentally verified with the prototype dual-layer array composed of 16 loudspeakers. Excellent agreement between experiment and theory is achieved.
